I understand that live worms are very important for fish and especially fry. I bought some from my fish dealer and put them in a conatiner having holes and stuck it to the side of the tank. 
of course the fish won't eat all of it on the same day. it can last for 4 or 5 days. I would like to know how long shall I keep the worms? I mean don't they rot or die? shouldn't I get new worms every three day for example? is there anything that I should do to the worms in the container everyday to keep them healthy for my fish?
